CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of U.S. provisionalapplication Ser. No. 60/798,703 titled ELECTRIC FAN WITH MULTIPLE FACIALTREATMENTS, filed May 8, 2006 and is incorporated herein by reference inits entirety.

FIELD OF THE INVENTION

The present invention relates to the field of air displacement devicesand more specifically to the field of disguised air circulation devices.

BACKGROUND

A fan is common sight within homes and offices. However, simply becausethe sight of fan is common does not mean that it is a welcome sight.Fans are utilitarian objects that are infrequently structured to appealto the personal tastes of spectators. Common fans generally include abulky stand that supports a metal or plastic wire cage with fan bladesdisposed therein. Such objects rarely fit into the décor of a home oroffice building.

Fans that attract minimal attention are portable fans, as can be foundin U.S. Pat. Nos. 2,341,220; 2,725,184; and 2,811,304. Portable fanscommonly include a fan unit that is mounted onto a base that allows thefan to be tilted forward and backward, or sometimes allows onoscillating or rotational movement about a vertical axis. The fanusually includes a motor inside a motor housing for driving the fanblades and a motor actuating switch for actuating the motor.

Although portable fans are less likely to attract the attention of aspectator than their larger analogs, portable fans are stillrecognizable as fans—which is often unwanted in many decoration schemes.Therefore, there is a need for a portable fan unit that isunrecognizable as a fan.

SUMMARY

The present invention is directed to a portable air displacement devicehaving one or more aesthetic overlays that disguise its visible aircirculation properties. By portable, it is meant that the presentinvention is capable of relatively simple relocation from one point toanother. In a picture frame air displacement device embodiment of thepresent invention, the device includes a body, a stabilizer, areleasable faceplate, and an air displacement unit. The body includes abody cavity on its surface and a body chamber within. The body chamberis connected to an air outlet and an air inlet. The stabilizer of thepicture frame embodiment includes mechanisms and articles commonly usedin the frame art to brace a picture frame, such as a stand or a wallmount aperture. The releasable faceplate is a cover for the body cavitythat serves to accept an aesthetic overlay disposed within the bodycavity. Within the body chamber, the air displacement unit includes anyair circulation devices common in the air circulation art, but isdimensioned to fit within the picture frame embodiment's body, which iscomparable to a typical picture frame.

A motive air displacement device embodiment of the present inventionincludes a body, a stabilizer, a structurally prominent faceplate, andan air displacement unit. The body of the motive embodiment includes asubstantially solid body surface that masks both a minimally-sized airinlet and peripheral air outlet. Within the body is a body chambersupporting an appropriately-sized air displacement unit connected to theair inlet and air outlet. Upon the body, and near the air outlet, islocated a structurally prominent faceplate that supports a transformingaesthetic overlay, i.e. an aesthic overlay capable of altering itssurface detail. Suitable stabilizers for the motive embodiment will varywith the transforming aesthetic overlay, but might include a base, wallmount, rotatable stand, and the like.

A buried air displacement device embodiment of the present inventionincludes a body, a retractable faceplate with an aesthetic overlay, andan air displacement unit. The body defines an interior body chamberconnected to an air inlet and an air outlet, both of which arepositioned on the surface of the body. Affixed to the body is aretractable faceplate configured to selectively obstruct the air outlet.Upon the retractable faceplate is an aesthetic overlay, whether aseparate entity or integrated therein. The stabilizer includes anyarticle capable of supporting the buried air displacement device on asurface. Within the body chamber is an air displacement unit configuredto accept air from the air inlet to the air outlet.

A model air displacement device embodiment of the present inventionincludes a body that is an aesthetic overlay. The aesthetic overlay isadapted to mimic a natural object that would naturally includeapertures. Within the aesthetic overlay body is a body chamber thatconnects to the air inlet and the air outlet. The air outlet and airinlet are positioned to correspond to the natural aperture locations. Itis preferred that the air inlets and air outlets are masked by eitherprotrusions or recesses of material circumscribing the air inlets andair outlets. Within the body chamber is the air displacement device.

Therefore, it is an aspect of the present invention to present an aircirculation device disguised an object unrelated to air circulation.

It is a further aspect of the present invention to provide a disguisedand portable air circulation device.

It is a still further aspect of the present invention to provide an aircirculation device having a function unrelated to air circulation.

These aspects of the invention are not meant to be exclusive.Furthermore, some features may apply to certain embodiments or versionsof the invention, but not others.

DETAILED DESCRIPTION OF SELECT EMBODIMENTS

Referring first to FIG. 1, a picture frame fan 100 embodiment of the airdisplacement device is shown. The picture frame fan 100 includes a body102, a stabilizer (not shown), a faceplate 106, and an air displacementunit 110. The body 102 includes a body cavity 108 within its surface anda body chamber 112 within. The body chamber 112 is an interior voidwithin the body 102 of the device that includes passages that define anair outlet 116 and an air inlet 114.

The body 102 of the present invention acts as the protective housing forthe internal components of the device, and also contributes to thedisguised nature of the present invention. As can be seen in the pictureframe fan 100, the body 102 is configured to include an internal bodychamber 112, which is simply the space within the body 102. Upon thesurface of the body are apertures allowing fluid connection with thebody chamber 102, the air inlet 114 and the air outlet 116. The airinlet 114 allows air entrance into the body chamber 112, and the airoutlet 116 allows air egress from the body chamber 112.

The air displacement unit 110 is disposed within the body chamber 112.The air displacement unit 110 is a mechanism adapted to accept air froma first point and transport it to a second point. The preferred airdisplacement unit 110 of the present invention is a fan; however, fanalternatives, e.g. pumps, are part of the present invention. In thepresent invention the air displacement unit 110 is always sized, suchthat in conjunction with the configuration of the body 102, the airdisplacement unit 110 is obscured, sometimes selectively, by the body102 or some other component adjacent to the body. As FIG. 2 shows, inthe picture frame fan 100 the body 102 includes a surface that obscuresthe presence of the air displacement unit 110 to the degree that it isgenerally invisible to a casual viewer.

Beyond merely obscuring the air displacement unit 110, a faceplate 106,as FIG. 1 illustrates, releasably attaches within a cavity 108 formed bythe body 102 of the picture frame fan 100. The faceplate 106 braces anaesthetic overlay 118 that distracts attention from the air displacementaspects of the picture frame fan 100. The body 102 is configured toobscure the air displacement unit 110; and the aesthetic overlay 118serves to distract a casual observer into believing that the presentinvention is something other than an air circulation machine.

The faceplate 106 of the present invention includes an assembly adaptedto support and/or protect the aesthetic overlay 118 in its position onthe body 102 of the present invention. The faceplate 106 of the presentinvention may be: completely removable from the body 102; removable onlyat selected points to allow a hinged attachment to the body 102; orpermanently affixed to the body 102. At its simplest, the faceplate 106can consist of a glass cover adapted to cover a single surface of theaesthetic overlay 118 as FIG. 2 shows; or as FIG. 3 shows can include amultiple layer configuration that completely encases the aestheticoverlay 118. The means for accepting the aesthetic overlay 118 will varydepending upon the particular type of aesthetic overlay 118 contemplatedfor use with the present invention In the picture frame fan 100embodiment of the present invention, it is preferred that the aestheticoverly 118 include a picture, and that the faceplate 106 comprise aremovable assembly adapted to both completely encase the picture, and toform a size-generated interference fit with the body cavity (not shown)of the present invention. Other means for accepting the aestheticoverlay are compatible with the present invention, and may include, forexample: a faceplate having surfaces that define a sleeve for theinsertion of photographs, documents, and the like; a faceplate havingmagnetically attaching surfaces that using a magnetic field to secure aninterior aesthetic overlay; a faceplate having a hinged attachmentallows an aesthetic overlay to be placed therein. The body 102 can beadapted to accommodate these faceplates or any faceplate capable offulfilling one of the aspects of the present invention.

As is further illustrated by FIG. 3, the preferred version of pictureframe fan 100 includes one or more air outlets 116 about the peripheryof the body 102. It is preferred that these air outlets 116 be discreteapertures, each selectively obstructed one or more louvers 122. Thelouvers 122 are adjustably affixed to the body 102 in a manner that asurface of the louver contacts the flow of air passing through the airoutlet. The louvers 122 can be adjusted by hand, and their adjustmentguides the air released through the air outlet 116 to a directionspecified by a user in rotating the louvers. In versions of the pictureframe fan 100 having louvers 122, it is further preferred that theperiphery of the body surface, on the same face as the louvers, includea grooved design. This grooved design assists in disguising the presenceof the louvers. The preferred picture frame fan 100 further includes areleasable frame 120 that snaps on to and circumscribes an outer portionof the body 102.

The air displacement unit 110 of the present invention will vary withthe particular embodiment with which it is used. The air displacementunit 110 can include any mechanism capable of displacing and directingair in a given direction. In the preferred picture frame fan 100, theair displacement unit 110 is a twelve volt, 120 mm fan. Such a fan ispreferred as it possesses substantial power and airflow generation witha minimum of sound generation.

The air inlet 114 of the present invention includes one or moreapertures located on the body 102 in a position suitable to allow airentrance into the body chamber. The air inlets 114 comprise a minimumamount of space on the body 102 to minimize the recognition factor ofthe present invention's true nature. As is common is current fans, theamount of open space in the rear generally comprises the entire rearsurface, limited merely by grating thereon. With the present invention,air inlet—be it on the side, rear, or front—does not consume that entiresurface; rather it is minimized for purposes of disguising the nature ofthe present invention. It is preferred that the air inlet 102 includeonly the space necessary to allow an amount of airflow suitable to allowthe air displacement unit 110 to operate effectively. It is preferredthat the air inlet 114 and air outlet 116 are offset or spaced to adegree that prevents a viewer from seeing through the body 102 of thepresent invention.

The stabilizer 104 of the present invention is a device or structureadapted to steady the body 102 on a surface. In instances where thesurface that will most likely support the present invention is ahorizontal surface, the stabilizer preferably includes one of thefollowing: a base, which is material integrated within the body and isdimensioned to support the present invention; or a stand, which includesmaterial shaped to confer a high degree of stabilization with a minimumof material. In instances where the surface that will most likelysupport the present invention is a vertical surface, the stabilizerpreferably includes an aperture dimensioned to accept a nail, screw orother hanging article; or the body includes an integrally formed hangingarticles, such as a hook. The stabilizer 104 may include featuresallowing the present invention to be easily moved or adjusted, such as arotatable connection controlling pitch, yaw, or a combination of thetwo. Other stabilizers may be capable of actuating the present inventionin a tiltable, rotatable, slidable, or reversible fashion. In thepreferred picture frame fan 100 embodiment, the stabilizer 104 includesa wire fashioned to support the picture frame fan 100 on a horizontalsurface. Commercial embodiments may include two such wires: one to allowthe body a lengthened vertical appearance; the other to allow the body ashortened vertical appearance.

As the present invention includes an air displacement unit 110, thepresent invention includes a power source 124. As shown in FIG. 3, thepower source 124 can include an AC adapter, but a DC power source isadditionally within the bounds of the present invention as are manyother components used in conjunction with air displacement devices, e.g.sensors that adjust fan speed based on temperature.

The aesthetic overlay 118 of the present invention includes anyaesthetic design of adapted to disguise the present invention as adevice other than a fan. The present invention includes at least oneaesthetic overlay 118, and may include multiple aesthetic overlays 118as FIG. 4 shows. In the picture fan frame 100 embodiment of FIG. 4, thebody 102 of the fan 100 includes multiple facets, each capable ofsupporting an aesthetic overlay 118. As FIG. 5 shows, each aestheticoverlay 118 is supported by a faceplate 106 releasable from the body102; wherein each faceplate 106 is dimensioned to fit within a bodycavity 108. In the cube version of the picture fan frame 100 embodimentof FIGS. 4 and 5, the faceplate 106 is preferably made of a single paneof glass and can either be integrated onto the body 102 to allow theaesthetic overlay 118 to slide therein, or releasable from the body 102.

The primary aesthetic overlay includes generally two-dimensionalarticles such as photographs, visual works of art, postcards, stickers,characters, symbols, images, mirrors, and the like. Articles not capableof serving as aesthetic overlays include visual cues that indicate thatthe device is a fan, e.g. a trademark of a brand of fan. FIG. 6illustrates a transforming aesthetic overlay 218 of the presentinvention. The transforming aesthetic overlay 218 includes theattributes of the aesthetic overlay, but rather than rely purely ondesign to distract attention from the true nature of the presentinvention; the transforming aesthetic overlay relies on functionaldistractions such as the clock faces of FIGS. 6 and 7.

In the embodiment of the present invention illustrated in FIG. 6, theclock fan 200 embodiment, the transforming aesthetic overlay 218includes that of an analog clock face. The transforming nature, i.e. themotion of the aesthetic overlay in changing from one aspect to another,of the aesthetic overlay 218 is that of keeping time. As thetransforming aesthetic overlay 218 is that of real clock, a viewer willmore likely recognize the present invention as a clock rather than afan.

In the clock fan 200 embodiment, it is preferred that the air outlet 116spans the periphery of the clock fan 200, and the stabilizer (not shown)include either an aperture adapted to accept an article adapted to hangthe clock fan 200 on a wall or include a hanging aperture upon the rearof the body 102 of the clock fan 200. As FIG. 7 illustrates, the presentinvention could further support a transforming aesthetic overlay 218 ofa more complex nature. The transforming aesthetic overlay 218 caninclude multiple functional devices, such as a digital clock face, atelevision screen, a light, and other devices unrelated to fans.

As embodiments of the present invention utilizing transforming aestheticoverlays include functional aesthetics, the ability to alter thefunctional aesthetics will not be necessary. Unlike the picture framefan embodiments of the present invention, the embodiments of the presentinvention utilizing a transforming aesthetic overlay need not beamenable to aesthetic overlay substitution. Thus, removable faceplatesor faceplates adapted to accept multiple aesthetic overlays may be usedwith transforming aesthetic overlay embodiments, but are not necessary.

As FIG. 8 shows, the clock fan 200 embodiment, like other transformingaesthetic overlay embodiments, includes the body 102, air displacementunit 110, air inlet 114, and air outlet 116 of the present invention.The body 102 of the clock fan 200 is dimensioned to appear as a clock,rather than a fan. The body 102 is substantially closed for thatpurpose, as is preferred for all body types of the present invention. Bya closed body, it is meant that the body 102 includes more closedsurface related to the object for which the present invention isdisguised to resemble than open surface like that of a fan. For analogclock fan embodiments, it is preferred that the body 102 include aflattened cylindrical appearance typical of wall clocks. The air outlet116 comprises multiple apertures about the periphery of the transformingaesthetic overlay 218 and point in the same direction as the face of thetransforming aesthetic overlay 218. The air inlet 114 of the clock fan200 embodiment includes one or more apertures leading air to the bodychamber disposed within the body 102 of the clock fan 200.

FIG. 9 illustrates a buried fan 300 embodiment of the present invention.The buried fan 300 embodiment includes the body 102, stabilizer 104, thefaceplate 106 retractably affixed to the body, and the air displacementunit 110. As FIG. 9 shows, the faceplate 106 of the buried fanembodiment is positioned onto the body 102 of the buried fan in a mannerthat selectively blocks the air outlet 118. By selectively blocking, itis meant that the faceplate 106 can accept multiple positions upon thebody 102 where one of the positions substantially blocks the air outlet118, and at least one more position where the faceplate 106 exposes theair displacement unit 110 therein to the environment. In the hingedembodiment shown in FIG. 9, the faceplate 106 can occupy a firstposition where the door swings into a position that completely obscuresthe air displacement unit 110 from sight. In a second position thefaceplate 106 opens to allow the air displacement unit 110 the abilityto maximize its air circulation ability. In the buried fan 300embodiments, it is not required that the faceplate 106 completely blockthe air outlet 118 in all positions; the faceplate 106 should occupy atleast one position that allows very limited access to the body chamber108 of the buried fan 300. The aesthetic overlay 118 of the picturedembodiment includes wood paneling, which disguises the fan as an articleof furniture. The stabilizer 104 is simply a base portion of the fan 300adapted to position the fan 300 upright.

Embodiments of the present invention may further include ornamental fanblades. As shown in FIG. 9, portions of the air displacement unit 110may include, for example, one or more lights located thereon. When theair displacement unit 110 is a fan, the fan blades could include atransparent body.

The embodiment of the buried fan 300 shown in FIG. 10 includes anaesthetic overlay 118 having a mirror on the body 102 supported by arotatable version of the stabilizer 104. The body 102 includes a shapethat simulates that of a woman's vanity mirror. The aesthetic overlay118, i.e. the mirror, is integrated within the faceplate 106, which ishingedly attached to the body 102.

FIG. 11 shows a model embodiment 400 of the present invention. The modelembodiments utilize the aesthetic overlay 118 that mimics a decorativeobject with an air displacement unit (not shown) disposed within. In themodel embodiments, the aesthetic overlay 118 covers substantially theentire present invention and acts as a housing. The aesthetic overlay119 of the model embodiments includes any non-fan shape that wouldnaturally include multiple apertures. Multiple apertures must exist inthe article that the aesthetic overlay mimics because these aperturesform the air inlet(s) 114 and air outlet(s) 116 of the model embodiment400. The embodiment of FIG. 111 is that of a doll house using thechimneys and windows of the dollhouse as an air inlet 114 and air outlet116, respectively.

Both the air inlets 114 and air outlets 116 of the model embodiments arepreferably situated proximate to structural recesses and protrusions tofurther hide the air circulation aspects of the present invention. Asthe air inlet or air outlet is masked by a protruding or recessed, theline of sight of an observer in peering into the innards of the presentinvention would be more greatly obstructed. Such masked apertures arepreferred, and are present in the device of FIG. 11: the air inlet ismasked within a protruding chimney; and the air outlet is masked withinthe recess of a window. The apertures of the model embodiment exist inplaces where the apertures would exist in an article which the aestheticoverlay mimics 118. The incoming airflow a thus, enters the presentinvention via seemingly natural apertures; and the outgoing airflow βexits the present invention through seemingly natural apertures.

As FIGS. 12 a and 12 b show, the air inlets lead directly to the airdisplacement unit 110. The air displacement unit 110 then urges the airthrough the air outlet 116. As FIG. 12 b shows, the present inventioncan further be adapted to include an air filter 198 obstructing an airflow path to the clean the air from unwanted contaminants. Preferredfilter materials may include dense fiberglass or polyester media,pleated media, HEPA, activated carbon, cotton gauze, vegetable fibers,synthetic fibers, charged plastic film or fiber, or any other aircleaners used in the art of air purifying. In place of, or inconjunction with an air filter 198, a fragrance injection device may beincluded in the air flow path. As FIG. 13 shows, the air inlet 114—orthe air outlet (not shown) for that matter—may include safety featuresrelevant to the present inventions operation such as screens. Theaesthetic overlay 118 of the model embodiment 400 can include anyoverlay that mimics a non-fan shape that could potentially includenatural apertures. In the doll model embodiment 400 of FIG. 14, anaesthetic overlay 118 adapted to mimic a human head includes the airinlet 114 and air outlet 116 of the present invention 400. The aperturesof the doll are masked within protruding facial features that assist inobscuring the presence of the apertures: the air inlet in the ears; andthe air outlet in the mouth. Further preferred aesthetic overlays mayinclude replications of animals.

FIG. 14 further illustrates a doll model embodiment equipped with asensor 196. The sensors of the present invention can include a motionsensor, body heat sensor, or an ambient temperature sensor. When usedwith a device of the present invention, the sensor would allow automaticfan actuation.
